Out of doors, ice, snow and freezing humidity can impair the proper function of technical installations. Here are three examples of infrared ensuring continued operation despite bad weather.
Gas turbines are throttled if filters are iced up.
To function properly, gas turbines need air for combustion. However, that air must be free from dust and other particles and is, therefore, always filtered. Cold and wet intake air in winter months can easily cause icing-up of the filters.
The filters then let little air pass through and the gas turbine has to be throttled or switched off – of all times in the season it is needed most. Mostly, the filters used are made of fleece, and often they consist of many small units inside a large filter
housing. Gas turbines are supplied with intake air from the outside, and especially at low outside temperatures combined with cold and wet air, the fleece filters can easily ice up. Therefore, the filters need to be protected to preserve the filtering effect and the air flow.
A British plant manufacturer has tested different anti-icing systems and decided to use a Heraeus Noblelight infrared system in a gas compressor plant in Germany.
The tests showed that an infrared module consumes less energy and is easier to install than other technologies. Three modules were installed, which are controlled by a thermostat that switches the emitters on when the outside temperature drops below a certain value and off again if the temperature reaches a preset value. The infrared modules are compact and very robust, and reliably function even under clammy conditions.
Gates of locks can no longer be used if they are iced up.
Shipping must stop if locks are iced up. At six weirs with locks in the Danube and the river Inn, Heraeus Noblelight infrared emitters make sure the locks can be operated also in severe winters.
The infrared emitters are installed horizontally at the weirs' lower sluices. Splash water cannot affect quartz glass infrared emitters, because quartz glass has a very small thermal expansion coefficient, and hence is very well resistant to thermal shocks.
The electrical connections are protected against water by a patented housing (made by the Heraeus customer Elektro Neumayer).
Iced coal cannot be moved.
Bulk goods such as ore or coal, which are transported by rail in metal cars, may freeze together into large lumps in cold and wet weather. Doors and flaps cannot be opened and it is difficult to empty the cars completely. Infrared heat can help here. The cars are heated from the outside, so that the coal lumps thaw.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
